MEGIS has lot maps for most towns on their website that will import into Google earth. The exact lines can be a little inaccurate but it will give you a good idea. That will tell you tax map/lot number. From there you can cross reference with the towns tax commitment book.

Ask for permission if you can, be aware of the season laws, as well as being 300+ft from buildings. In the thick maine woods you can very easily be less than 300ft and not be aware of it.

Snowshoes are a hard thing to hunt as a beginner, and 100x harder once there's snow on the ground. Best bet is to look for tracks and do a slow still hunt from there. They are very easy to startle and they will run off quickly, however they tend to make a big loop back to their den so sometimes hanging out or checking back in that area later can work successfully.

Be safe and good luck!
